TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 234,810, dated November 23, 1880. Application filed September 20, 1880. (No model.) Patented in Austria-Hungary March 11, 1880.

To all whom it may concern Be it known that I, GUSTAV RoMIsoH, of Austria, residing at Vienna, in Empire -of Austria, have invented certain new and useful Improvements in TobaccoPipes; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same.

In all pipes, nargilehs, 850., heretofore in use the lower layers of tobacco become saturated by the products of combustion and distillation penetrating them, and a great deal of tobacco is therefore rendered perfectly useless or receives a disagreeable, sharp, and unhealthy taste.

The object of my improvements is to obviate this defect; and to that end the invention consists, first, in a pipe-bowl, the combination of a removable combustion-chamber having a contracted combustion-zone and a tobacco-receptacle arranged to form an annular divingflue between'it and the pipe-bowl and feeding devices to feed the tobacco to said combustionzone, all as hereinafter setforth; second, in a pipe-bowl, the combination of a removable tobacco-receptacle arranged to form an annular diving-flue between it and said bowl, and provided with a foot or base to form a chamber below said receptacle and between itand the pipebowl, aremovable combustion-chamber having a contracted combustion-zone, and feeding devices for the tobaccoto feed the latter to said zone, all as hereinafter set forth; third, in a pipe-bowl, the combination therewith of a removable combustion-chamber, a removable tobacco-receptacle, and removable feeding de vices to feed the tobacco to the combustionchamberfall as hereinafter fully described; and, last y, the invention consists in certain minor (.etails of construction and arrangement,a l as hereinafter fully described, and as illustrated in the accompanying sheet of drawings, in which Figure 1 is an elevation, and Fig. 2 a longitudinal section, of pipe-bowl embodying my improvements. Fig. 3 is a longitudinal sec tion thereof, showing the position of parts when filled wit-h tobacco. Figs. 4 and 5 are elevations of the combustion and tobacco cylinders. Fig. 6 is alongitudinal section of the bowl, showing the bowl with the combustion and tobacco cylinders removed. Figs. 7 and S'are transverse sections on lines a I) and c 01, respectively, of Fig. 3. Figs. 9, 10, 11, and 12 show a slight modification in the arrangement of the parts.

In the above drawings like letters of reference are employed to indicate like parts wherever such may occur, and in these figures A represents the bowl ofthe pipe, which may'be made of any suitable material and of any desired shape, exteriorly as well as interiorly, so far as this latter construction may be consistent with the proper function of the parts combined therewith.

I preferably make the interior a of the bowl A of cylindrical form, but of unequal diameter, the latter being wider from a point, a, to the top of the bowl, as shown, Figs. 2, 3, and 7, for purposes hereinafter explained.

The upper end of the bowl is provided with a threaded metallic sleeve, a upon which is screwed the combustion-cylinder B, provided with a lid, 1), a flaring mouth, I), and a lower cylindrical combustioirchamber, b forming between the two the contracted neck shown at g. V

The cylinder B is provided with an annular sleeve, b screw-threaded interiorly and adapted to be screwed upon the sleeve at the upper edge of the bowl A. The exterior diameter of the combustionchamber of the cylinder B is smaller than the upper interior diameter of the pipe-bowl, thus leaving an annular space, h, as shown, Figs. 2, 3, 7, and 9.

G is the tobaccoreceptacle, also of cylindrical form, provided with a footor projecting base, 0. The exterior diameter of this receptacle is slightly less than the interior smaller diameter of the bowl A, so as to form the annular space b*, as shown, forming a downward or diving draft-passage for the products of combustion.

The height of'the tobacco-receptacle is such that when in position in the bowl Athete will be a narrow annular aperture or space, I, between the upper face of said receptacle and the lower face of the combustioncylinder B, as shown, Figs. 2, 3, and 9.

D is a follower, composed of a cylindrical casing open at bottom and closed at top, containing a coiled spring, one end of which is attached to the top 61 of the casing D, and the other free end of said spring bears against the bottom of the tobacco-receptacle G, as shown, Figs. 2 and 3.

The end of the spring E is preferably made to project through the top of the casing D, and has its end formed into a loop, which may serve as a handle to lift the follower and spring out of the tobacco-receptacle and pipebowl for the purpose of removing any tobacco, dust, or ashes that may accidentally enter below the follower.

To prevent as much as possible any to bacco or ashes passing below the follower D, I form the casing as shown, Figs. 2 and 3 that is to say, with its upper and lower edges fitting snugly against the interior walls of the tobacco-receptacle O, and reducing its diameter at a point, d, immediately below the upper closed end of said casing to form an annular chamber, so that any tobacco or ashes that may accidentally pass between the closed top (Z and the walls oftobacco-receptacle will be arrested by the lower expanded part of the casing D, that, likeits top,is made to fit.sufficiently tight against the interior wall of the receptacle 0 without thereby impeding its movements therein.

Instead of making the receptacle 0 a separate part of the pipe-bowl, this and said bowl may be formed of one piece, as shown, Figs. 9, 10, 11, and 12.

It will be seen that the arrangement of parts is not necessarily confined to the particular form of pipe-bowl shown in thedrawings, and that they may be applied to other forms, such, for instance, as those usually employed in conjunction with nicotine-reservoirs, and also that the interior configuration of the bowl need not necessarily be cylindrical, nor is it absolutely necessary that the sleeves to b should be provided with screwthreads, as these may be arranged to fit sufficientl y tight without such threads to hold them in proper position relatively to each other.

The operation of the devices may be briefly stated as follows: The tobacco-receptacle O 'bein g charged with tobacco, either through the flaring or hopper mouth of the cylinder B or by removing said cylinder, the spring E, together with its casing, is depressed, the spring'tending to press the casing 1) and the charge of tobacco above it upward to fill the combustion-chamber b of the cylinder B. The latter chamber being contracted at g, the annular shoulder formed by such contraction will arrest the upward movement of the tobacco under the action of the spring. The parts being now in the position shown by Fig. 3, the tobacco is ignited in the usual manner, and the products of combustion, instead of passing, as usual, through the entire charge, will pass only through that portion within the combustion-chamber, escaping through the narrow annular aperture 1 between the latter and the top of the tobacco-receptacle O, and thence into the enlarged annular draft-chamber h, from which these products pass downward through the contracted annular passage b and thence out through the neck A into the stem.

By providing the tobacco-receptacle O with a foot, 0, I form at the base of the bowl a nicotine-chamber, z, from which the nicotine and saliva may be readily removed.

As the tobacco is consumed fresh tobacco is fed to the chamber b by the follower D under the action of its spring E.

The advantage of this construction and arrangement of pipe-bowl will be readily understood from what has been said above.

Having now described my invention, what I desire to claim, and secure by Letters Patent, is-

1. The combination, with the pipe-bowl and a tobacco-receptacle arranged to form an annular passage between it and the pipe-bowl, of a removable combustion-chamber, having the contracted combustion-zone g, and devices to feed the tobacco thereto, arranged and operating as and for the purpose specified.

2. The combination, with the pipe-bowl, the tobacco-receptacle, and tobacco-feedin g devices, of the removable combustion-chamber B, having the contracted part g, and arranged relatively to the tobacco-receptacle to form the annular passage Z between it and said re oeptacle, all arranged and operating as and for the purpose specified.

3. The combination, with the pipe-bowl, of a removable combustion-chamber, a removable tobacco-receptacle, and feeding devices to feed the tobacco to said combustion-chamber, all arranged and operating as and for the pun pose specified.

4. The combination, with the pipe-bowl, of the removable combustion-chamber, the removable tobacco receptacle, and removable feeding devices to feed the tobacco to the combustion-chamber, all arranged and operating substantially as described, and for the purpose specified.

5. The combination, with the bowlA, of the removable receptacle 0, provided with a foot, 0, as and for the purpose specified.

6. The combination, with the receptacle 0 and follower-casing D, of the springE, projecting through the top dand having loop 0, substantially as and for the purpose specified.

7. The combination, with the bowl A, the cylinder B, having a flaring month, a. combustion-chamber, b and a contracte part, g, between the two, of the receptacle G, we follower D, and spring E, all arranged and opcrating substantially as and for the purpose specified.
